ALONZOT. BOONE, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF OF .HIS RIGHT TO GEORGE G. BENEDICT, OF SAME PLACE.

LOCK FOR BOTTLES,'&.0.

SPECIFICATION forming part of Letters Patent No. 228,170, dated June 1, 1880. Application filed September 20, 1879.

clear, and exact description thereof, reference being had to the accompanying drawings, of which Figure 1 is a partial side elevation of a bottle locked with my device; Fig. 2, a vertical central section' of the same; Fig. 3, a plan view of the top; Fig. 4, a plan view of the interior below the top; Fig. 5, an inverted view of the top; Fig. 6,a horizontal section on the line at m, Fig. 1; Fig. 7, a detail view, and Fig. 8 a "iew of the key.

My invention relates to a device for locking bottles and the like and permitting the abstraction of their contents only by the person possessing the key. I design it especially for such as contain liquors; but there is no reason why its application should not be very greatly 6Xt611(l( The essential requisites of a device for the purpose named I deem to be the following, and these the one which I have contrived aims to supply: first, that it should be simple and compact, not consisting of separate or detached parts; second, that it should, if desired, be capable of closing the bottle without looking it; third, that it should operate to lock the bottle without the aid of a key; and, fourth, that when once looked it should be incapable of being opened otherwise than by means of the key.

To the above ends my invention consists, first, in a screw-cap having one or more vertically-sliding bolts on its periphery, which bolts are forced downward by means of an arm operating internal mechanism and proand which bolts, when the cap is in placeupon the bottle, enter notches or recesses in a collar on the bottle neck below the cap, thus preventing the cap from being unscrewed, and which are drawn upward only by means of a key entering an aperture in the said cap, the said arm operating only in one direction, whereby it serves to look but not to unlock the device; and, furi thermore, in the various details of mechanism by which my invention is carried into effect.

In the drawings, A is a bottle, flask, or demijohn, having a threaded neck; and B, a cap comprising an upper and alower chamber, formed by means of a diaphragm, O, with a facing, D, of cork or other suitable material.

is threaded, in order that thecap may screw upon the neck of the bottle and bring the cork facing hard down upon the orifice.

E is a pan fitting loosely chamber of the cap, and maintained in a central position, and made capable of revolving readily by resting upon a pivot, m, in the center of the diaphragm U. The pivot may, however, be dispensed with, if desired. The wall of this pan is slotted obliquely on opposite sides from top to bottom, n a being the slots, and is also recessed from the edge of each slot to the shoulder 0. In the bottom of the pan, and rigidly fixed thereto above the pivotal point, is a stud or projection having recesses p to receive the end of a key.

F is a bar extending entirely across the pan E, and having acircular aperture, q, in its center, (where it may be broadened, as shown, to avoid any sacrifice of strengtln) adapted to fit around the projection containing the recesses key. pan, extends through slots r in opposite sides of the upper chamber of the cap B, and is continued into the bolts G G at right angles to the bar F, and extending down the outside of the said cap, the bolts G G being of such length that when the bar F lies on the bottom of the pan E they will project below the lower edge of the cap B.

I deem it preferable to inclose the bolts G within sleeves 8, formed upon the sides of the cap B.

H is a revolving disk set centrallyin the top of the cap B, and having a slot, t, for the passage of the key. An arm, I, is rigidly attached to the under side of the said disk H, and projects horizontally outward, emerging through an elongated slot, at, just below the upper edge of the cap B. A collar, K, which within the upper.

19, and permitting the en trance thereto of the This bar rests upon the edges of the The interior of the wall of the lower chamber may either form part of the bottle or be a separate attachment, surrounds the neck of the bottle, and is provided at intervals withrecesses c, which the bolts G enter when the device is locked.

When the device is unlocked the bar F lies across the pan close to the oblique slots therein, the arm I against the left of the elongated slot u, and the shoulder 0 of the pan against the arm I. The operation therefore is as follows: The bottle or demijohn havingbeen filled the cap is screwed into place and the bolts G caused to register with the recesses o in the collar K. The arm I is then swung to the right the whole length of the slot it, thus turning the pan E by means of the shoulder 0, and causing the slots at to engage the bar F and force the same downward by means of the upper inclined plane formed by the slot at. This, of course, carries the bolts Gr down into the recesses 01, thus preventing the cap from being unscrewed. It is obvious that the device cannot be unlocked by reversing the movement of the arm I, since there is no corresponding shoulder on the pan for the said arm to act against in the contrary direction, and the arm, therefore, may now be moved back and forth without producing any effect whatever; and the only possible way of opening the bottle other than by breaking is with the key L. This is inserted through the slot t into the key-recesses p, which register with the said slot it when the arm G is to the right of the slot a, and upon being turned causes the pan E to revolve, forcing the bar F upward by means of the lower inclined planes formed by the slots, and thus withdrawing the bolts G from the recesses 12 and permitting the unscrewing of the cap.

While I prefer to use two bolts G, as shown, it is obvious that the same effects may, if preferred, be produced with a single one; also, as before implied, a metal collar may be employed below the thread upon the neck of the bottle, with recesses or sockets for the reception of the bolts.

The edge of the pan E may, if desired, be cut away only on one side, forming but one shoulder 0, which is sufficient for every purpose, since only one ever becomes operative. By having two shoulders the pan is in position to work whichever way it is dropped into the upper chamber, and therefore no particular care need be exercised in inserting it. This is the only reason for forming the two shoulders.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination of a recessed collar on the neck of a bottle or demijohn, a screw-cap fitting above the said collar, vertically-sliding bolts upon the sides of the said cap, and locking mechanism inclosed within the said cap, substantially as described, and for the purpose set forth.

2. The combination of a recessed collar fixed to the neck of a bottle, a screw-cap fitting over the mouth of the said bottle, vertically-sliding bolts on the sides of the said screw-cap, locking mechanism inclosed within the said screw-cap, operating the sliding bolts, and an arm actuating the said locking mechanism and projecting through a slot in the said cap, whereby the device is locked, substantially as described.

3. The pan E upon the base of the upper chamber of the screw-cap B, and provided with the oblique slots a, shoulder 0, and keyrecesses p, combined with the bar I*, having the opening q in its center and continued at right angles into bolts G, the revolving disk II in the top of the screw-cap, having a slot, t,

and the arm I, rigidly attached to the under side of the said disk H, and projecting through a. slot, u, in the side of the screw-cap, the whole being constructed and arranged to operate substantially as described.
